WASHING-MACHINE sesame.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed May 3, 1916. Serial No. 95,225.

To all whom it may concern Be it known that 1, JOHN AQPARMn 'rIERQ a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented new and useful Improvements in Vi ashing-Machine Gearing, of which the following is a specification.

This invention relates to improvements in washing machine gearings and has particular application to hand operated gearing for driving the dasher shaft. y

In carrying out the present invention, it is my purpose to provide washing machine gearing which will embody in its construction, among other features, a main drive shaft and gear connections between such shaft and the dasher shaft whereby the dasher shaft may be oscillated in the continued rotation of the main shaft.

It is also my purpose to provide a housing for inclosing the gear connections between the main shaft and the dasher shaft whereby such gear connections will be protected against water, dirt and the like.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claim.

In the accompanying drawing; Figure 1 is a View in side elevation of washing machine gearing constructed in accordance with the present invention. Fig. 2 is a longitudinal sectional view therethrough. Fig. 3 is a cross sectional View through the same. Fig. 4 is a horizontal sectional view.

Referring now to the drawing in detail, 1 designates a cylindrical housing having the lower end closed and the upper end provided with a hinged cover 2 capable of movement to open position so that access may be had to the interior of the housing. Formed on the housing 1 adjacent to the lower end wall thereof at diametrically opposite points are outwardly projecting lugs 3 whereby the housing may be secured in position upon the tub or receptacle.

. Formed on the housing 1 at a point between the lugs 3 and projecting outwardly over the housing is a bracket arm 4;, while secured to the outer end of the bracket arm 4; and uprising therefrom is a bearing 5 alining with bearings openings 6 formed in the housing 1 at diametrically opposite points.

J ournaled in the horizontal bearing 5 and the alining bearing opening 6 is a main shaft 7 extending through the housing 1 and splined upon the shaft 7 within the housing is a spool shaped casting 8 having the inner surfaces of the end pieces thereof formed with bevel teeth 9, and the central portion formed with a spiral groove 10.

11 designates a vertical dasher shaft having the upper end journa led in the lower end wall of the housing 1 and the bottom end equipped with a dasher 12 of suitable construction designed to project into the tub or receptacle. The upper end of the dasher shaft 11 projects into the groove 10 and keyed upon such end of the dasher shaft is a bevel gear 13.

The teeth 9 on each end piece of the spool shaped casting 8 are arranged about only one half of such end piece and are disposed at the side of the body of the spool opposite from the teeth on the other end piece. These sets of teeth are adapted to engage the bevel gear 13 alternately and the groove 10 is so formed that upon one-half a revolution of the main shaft 7 the teeth on one end piece of the casting 8 engage the gear 13, while in the remaining half revolution of the main shaft the teeth on the other end piece engage the bevel gear 13, while the first teeth are disengaged from such gear, owing to the rotation of the casting and the upper end of the dasher shaft engaging the groove 10.

One end of the main shaft 7 projects beyond the bearing 5 and fixed upon such end is a hand wheel 1% provided with an outwardly projecting eccentrically disposed handle 15 whereby the main shaft may be rotated. Secured to the main shaft at the outer sides of the bearing opening 6 are thrust collars 16 that act to hold the main shaft against longitudinal movement.

I claim:

Washing machine gearing comprising a vertical dasher shaft, a horizontal main shaft, a spool shaped casting splined upon said main shaft and having the end pieces thereof formed with sets of teeth respectively and the central portion formed with a spiral groove that receives the upper end of the main shaft, '21. bevel gear on the upper end of said main shaft adapted to be engaged by said sets of teeth alternately, means for rotating said main shaft whereby said casting will be revolved and moved longitudinally to alternately engage said sets of teeth With said bevel gear whereby an oscillatory motion will be imparted to said dasher shaft, a cylindrical housing inclosing the connections between said main shaft and dasher shaft and having a closed lower end and the upper nd provided With a hinged cover, said housing being formed With diametrically opposed bearing openings in WhlCh said ma n shaft is JOurnaled, a bracket and thrust collars secured to said main shaft at the outer ends of said bearing openings.

In testlmony whereof I afiix my signature.

JOHN A. PARMENTIER.
